News travelled as far as the Kansas City Star
last week when Legionella, the bacteria that causes Legionnaire’s Disease
, was found in ice machines at the University of Pittsburgh Medical Center’s Presbyterian Hospital.
According the piece reported by the Associated Press, officials at UPMC Presbyterian
were stumped when the hospital’s water system tested negative for Legionella though one patient died and two were sickened with the disease last year. The bacteria usually develops in warmer water.
UPMC spokeswoman Wendy Zellner said refrigeration compressors gave off heat raising the temperature in the water reservoirs of the affected ice machines and warmed the water enough for Legionella to develop.
